These tables are updated every twenty minutes
at 10 minutes, 30 minutes, and 50 minutes after the full hour.
If you see tables that are not up to date, your browser may be displaying
the cached version instead of the fresh version available on our server.
You may need to press SHIFT and click on RELOAD to force your browser
to refresh the tables. The mini charts show the prices of the last fourteen
days. Click on any of the three mini charts to obtain a PDF version
